Updating data of the rain

[casetta]

Hi,
now i noticed that i have a new issue.
I use "Heavy Weather" 1.5.2 and GraphWeather 2.0.321
I have noticed that the values ​​of rainfall are received from GW with a few hours late.
I mean rainfall 1h and rainfall 24h.
HW shows these values ​​in real time correctly but GW receive them about two hours late.
However GW receives all the other values ​​of pressure, temperature and wind correctly.
Can someone help me?
Thanks

I made more precise tests.
The data of rain on 24 hours and on 1h, which are reported on the stylesheet, are exactly one hour late, the stylesheet uses the variables "Current [rainfall_24h]" and "Current [rainfall_1h].

The strange thing is that the graphics, which instead use the variables "Max [rainfall_24h]" and "Max [rainfall_1h]", are accurate and timely.

I tried to change the time setting of the station, but there are no changes.

Please, someone could help me?
